FINISHING-ROLL.

SPECIFICATION forming part of Letters Patent No. 546,868, datedSeptember 24, 1895.

Application filed April 19, 1895. Serial No. 546,398 '(No model.)

To all wftom 2325 may concern:

Be it known that I, IRA VAUGHN, residing in Salem, county of Essex, andState of Massachusetts, have invented an Improvement in Finishing-Rolls,of which the following description, in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

This invention relates to a novel construction of roll for operatingupon hides or skins, and is an improvement upon operating-rolls of theclass shown and described in United States Letters Patent No. 274,859,dated March 27,1883, and No. 344,069, dated June 22, 1886.

The operating-rolls shown in the patents referred to are provided with aplurality of substantially-long threads or flanges extending in oppositedirections toward the ends of the roll, and with smaller flanges orthreads which extend from the main flanges or threads at an anglethereto. The long flanges or threads of the rolls shown in thepatentsreferred to extend from a transverse line at the center or otherpoint intermediate of the ends of the roll and run or extend in oppositedirections to the ends of the roll at the same or substantially the sameangle. These rolls are now employed for unhairing, fleshing, puttingout, stretching, 850., and are efiective therefor 5 but practice hasdemonstrated that when the hide or skin has been put through theputting-out machine-such, for instance, as shown and described in UnitedStates Patent No. 444,173, dated January 6, 189lthe hide or skin is putout or stretched, but not in a satisfactory manner, owing to the factthat the stretch on opposite sides of the transverse line is in the samedirection, and as the neckand-shoulder portion of the hide is of adifferent shape from the body portion the stretch of theneck-and-shoulder portion in the same direction as the body portionleaves in the hide or skin the original fullness or bag formed by theshoulders, whereas the original fullness in the body portion formed bythe hips of the animal is taken out.

This invention has for its object to provide a construction ofoperating-roll by which the bag or fullness in the neok-and-shoulderportion of the hide, and which is left in the hide or skin in theputting-out operation, may be taken out and the hide or skin furtherenlarged or stretched to the extent of such bag or fullness; and thisoperation, which is now performed by hand, I prefer to distinguish fromthe putting-out operation by hereinafter referring to it as thefinishing operation and to designate the improved roll as thefinishing-roll.

In accordance with this invention the finishing-roll is provided withtwo sets of vanes, flanges, threads, or blades extended spirally inopposite directions from or about a transverse line through the roll,preferably at or about two-thirds its length, the short set of vanesbeing extended at a different angle from the long set of vanes and eachshort vane preferably having its co-operating long vane, whereby thebody of the hide or skin is stretched and smoothed in one direction byall the long vanes and the neck and fore part of the hide or skin arestretched and smoothed out in an opposite direction by allthe shortervanes, but at a dilferent angle, which takes out the bag or fullnessformed by the shoulders.

Figure 1 is a plan view of a pair of finishing-rolls embodying thisinvention; Fig. 2, end elevations of the rolls shown in Fig. 1, and Fig.3 an outline of a hide to more clearly illustrate the operation of thefinishing-rolls.

In the present instance two finishing-rolls A A are shown, which inpractice are and may be substituted for the putting-out rolls shown inthe Patent No. 444,173, above referred to, and the machine thus changedmay be used for finishing the operation on the hide or skin performed bythe putting-out machine.

The finishing-rolls A A are of like construction, and each roll isprovided on its periphery with two sets of spirally-arranged vanes,blades, flanges, or threads to a, extended from a transverse line orplane through the roll toward-its opposite ends, but at different angleswith relation to said transverse line or plane.

The transverse line or plane referred to in the present instance islocated substantially one-third the length of the roll from one end ofthe same, the long vanes a being substantially twice as long as theshort vanes a. The transverse line or plane through the finishingrollcorresponds substantially to the line 00 00, Fig. 3, and the long vanesa act on the body portion 2 of the hide or skin, while the short vanes aact on the shoulders and neck portion 3 of the hide or skin, but thestretching action of the short vanes a is at a different angle from thelong vanes a, and this action of the finishing-roll 011 the hide or skinmay be better understood by supposing that the long vanes a stretch thebody portion of the hide or skin in the direction indicated by the arrow20, Fig. 3, and that the short vanes a stretch the shoulders and neckportion in the direction indicated by the arrow 22.

The long vanes a, it will be noticed, wind about the roll and have lesspitch than the short vanes a.

It will be understood that the vanes not only are to lengthen the hideor skin, but are to widen at the same time.

It will be noticed that in the finishing-roll herein shown each longvane or blade at has its co-operating short vane or blade (1,, so thatthe two vanes or blades approximate one continuous Vane or bladeextended from end to end of the roll, but in opposite directions from atransverse plane or line through the roll and in dififent angles withrespect to said plane and to each other, which is the construction Iprefer to use.

p I claim- 1. A finishing roll provided with two sets of vanes or bladesextended in opposite directions from a transverse line or plane throughthe roll and at different angles thereto and to each other, for thepurpose specified.

2. A finishing roll provided with the long vanes a and with the shortervanes a extended in opposite directions at diiferent angles, the longvanes being located on one side of a transverse line through the roll,and the short vanes being located on the other side of said transverseline, and each long vane having its co-operating short vane,substantially as and for the purpose specified.

8. A finishing roll provided with two sets of vanes or blades extendedin opposite directions from a transverse line or plane through the roll,one set of vanes having a diiterent pitch from the otherset of vanes,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. V

IRA VAUGHN.
